Perpetual drought across the coastal regions of Southern California has left raptors emaciated, contributing to silence in their once populated breeding grounds.

In regions usually swarming with hawks and other birds of prey, nests remain empty, Audubon California Bird Conservation Program Director Andrea Jones said.

"We're losing an entire generation," Jones said. "This has been going on for a while and we have seen significant declines in species including red-shouldered hawks, golden eagles and White-tail Kites."
